ImageMagick® is a software suite to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.

[Introduction to the ImageMagickObject COM+ Object • Build ImageMagickObject From Source]

Introduction to the ImageMagickObject COM+ Object

The ImageMagickObject is a COM+ compatible component that can be invoked from any language capable of using COM objects. The intended use is for Windows Scripting Host VBS scripts and Visual Basic, but it is also available from to C++, ASP, and other languages like Delphi, Perl and PHP.

-

The ImageMagickObject COM+ component provides access to the compare, convert, composite, mogrify, identify, montage, and stream tools, efficiently executing them as part of your process, rather than as external programs. The way you use it is exactly the same. You pass it a list of strings including filenames and various options and it does the job. In fact, you can take any existing batch scripts that use the command line tools and translate them into the equivalent calls to the COM+ object in a matter of minutes. Beyond that, there is also a way to pass in and retrieve images in memory in the form of standard smart arrays (byte arrays). Samples are provided, to show both the simple and more elaborate forms of access.

CompositeLayers

-

CompositeLayers() compose first image sequence (source) over the second image sequence (destination), using the given compose method and offsets.

+

CompositeLayers() compose the source image sequence over the destination image sequence, starting with the current image in both lists.

+ +

Each layer from the two image lists are composted together until the end of one of the image lists is reached. The offset of each composition is also adjusted to match the virtual canvas offsets of each layer. As such the given offset is relative to the virtual canvas, and not the actual image.

+ +

Composition uses given x and y offsets, as the 'origin' location of the source images virtual canvas (not the real image) allowing you to compose a list of 'layer images' into the destiantioni images. This makes it well sutiable for directly composing 'Clears Frame Animations' or 'Coaleased Animations' onto a static or other 'Coaleased Animation' destination image list. GIF disposal handling is not looked at.

-

The pointers to the image list does not have to be the start of that image list, but may start somewhere in the middle. Each layer from the two image lists are composted together until the end of one of the image lists is reached. The offset of each composition is also adjusted to match the virtual canvas offsets of each layer. As such the given offset is relative to the virtual canvas, and not the actual image.

+

Special case:- If one of the image sequences is the last image (just a single image remaining), that image is repeatally composed with all the images in the other image list. Either the source or destination lists may be the single image, for this situation.

-

No GIF disposal handling is performed, so GIF animations should be coalesced before use. However this not a requirement, and individual layer images may have any size or offset, for special compositions.

+

In the case of a single destination image (or last image given), that image will ve cloned to match the number of images remaining in the source image list.

-

Special case:- If one of the image sequences is just a single image that image is repeatally composed with all the images in the other image list. Either the source or destination lists may be the single image, for this situation.

This is equivelent to the "-layer Composite" Shell API operator.

The destination list will be expanded as needed to match number of source image overlaid (from current position to end of list).

MagickCompositeLayers

+
+ +

MagickCompositeLayers() composite the images in the source wand over the images in the destination wand in sequence, starting with the current image in both lists.

+ +

Each layer from the two image lists are composted together until the end of one of the image lists is reached. The offset of each composition is also adjusted to match the virtual canvas offsets of each layer. As such the given offset is relative to the virtual canvas, and not the actual image.

+ +

Composition uses given x and y offsets, as the 'origin' location of the source images virtual canvas (not the real image) allowing you to compose a list of 'layer images' into the destiantioni images. This makes it well sutiable for directly composing 'Clears Frame Animations' or 'Coaleased Animations' onto a static or other 'Coaleased Animation' destination image list. GIF disposal handling is not looked at.

+ +

Special case:- If one of the image sequences is the last image (just a single image remaining), that image is repeatally composed with all the images in the other image list. Either the source or destination lists may be the single image, for this situation.

+ +

In the case of a single destination image (or last image given), that image will ve cloned to match the number of images remaining in the source image list.

It is basically equivalent to as MorphologyImageChannel() (see below) but without any user controls. This allows internel programs to use this function, to actually perform a specific task without possible interference by any API user supplied settings.

ImageMagick consists of more than 400,000 lines of C code and optionally depends on several million lines of code in dependent libraries (e.g. JPEG, PNG, TIFF libraries). Given that, one might expect a huge architecture document. However, a great majority of image processing is simply accessing pixels and its metadata and our simple and elegant implementation makes this easy for the ImageMagick developer. We discuss the implementation of the pixel cache and getting and setting image properties and profiles in the next few sections. Next, we discuss using ImageMagick within a thread of execution. In the final sections, we discuss image coders to read or write a particular image format followed by a few words on creating a filter to access or update pixels based on your custom requirements.

The Pixel Cache

-

The ImageMagick pixel cache is a repository for image pixels with up to 5 channels. The first 4 channels are stored contiguously and an optional second area follows with 1 channel. The channels are at the depth specified when ImageMagick was built. The channel depths are 8 bits-per-pixel component for the Q8 version of ImageMagick, 16 bits-per-pixel component for the Q16 version, and 32 bits-per-pixel component for the Q32 version. By default pixel components are unsigned quantities, however, if you use the high dynamic-range version of ImageMagick, the components are 32-bit floating point. The primary 4 channels can hold any value but typically contain red, green, blue, and alpha intensities or cyan, magenta, yellow, and alpha intensities. The optional fifth channel contains the colormap indexes for colormapped images or the black channel for CMYK images. The pixel cache storage may be heap memory, anonymous memory mapped memory, disk-backed memory mapped, or on disk. The pixel cache is reference-counted. Only the cache properties are copied when the cache is cloned. The cache pixels are subsequently copied only when you signal your intention to update any of the pixels.

When the pixel cache is initialized, pixels are scaled from whatever bit depth they originated from to that required by the pixel cache. For example, a 1-channel 1-bit monochrome PBM image is scaled to a 4 channel 8-bit RGBA image, if you are using the Q8 version of ImageMagick, and 16-bit RGBA for the Q16 version. You can determine which version you have with the ‑version option:

As you can see, the convenience of the pixel cache sometimes comes with a trade-off in storage (e.g. storing a 1-bit monochrome image as 16-bit RGBA is wasteful) and speed (i.e. storing the entire image in memory is generally slower than accessing one scanline of pixels at a time). In most cases, the benefits of the pixel cache typically outweigh any disadvantages.

    A great majority of image formats and algorithms restrict themselves to a fixed range of pixel values from 0 to some maximum value, for example, the Q16 version of ImageMagick permit intensities from 0 to 65535. High dynamic-range imaging (HDRI), however, permits a far greater dynamic range of exposures (i.e. a large difference between light and dark areas) than standard digital imaging techniques. HDRI accurately represents the wide range of intensity levels found in real scenes ranging from the brightest direct sunlight to the deepest darkest shadows. Enable HDRI at ImageMagick build time to deal with high dynamic-range images, but be mindful that each pixel component is a 32-bit floating point value. In addition, pixel values are not clamped by default so some algorithms may perform differently than the non-HDRI version.

However, you are welcome to use ImageMagick algorithms in your threads of execution with the exception of the MagickCore's GetVirtualPixels(), GetAuthenticPixels(), QueueAuthenticPixels(), or SyncAuthenticPixels() pixel cache methods. These methods are intended for one thread of execution only with the exception of an OpenMP parallel section. To access the pixel cache with more than one thread of execution, use a cache view. We do this for the CompositeImage() method, for example. Suppose we want to composite a single image over a different image in each thread of execution. If we use GetVirtualPixels(), the results are unpredictable because multiple threads would likely be asking for different areas of the pixel cache simultaneously. Instead we use GetCacheViewVirtualPixels() which creates a unique view for each thread of execution ensuring our program behaves properly regardless of how many threads are invoked. The other program interfaces, such as the MagickWand API, are completely thread safe so there are no special precautions for threads of execution.

    Always unlock the semaphore before returning from the png codec, either by a "return" or png_error(); changed all Magick*Exception() calls after setjmp() to png_error() to ensure proper cleanup (reference http://www.imagemagick.org/discourse-server/viewtopic.html?f=3&t=16883).

    2012-04-10 6.7.6-6 Anthony Thyssen <A.Thyssen@griffith...>
    +
    Fixed log known alpha*kernel normalization bug in morphology convolve.
    + Convolve kernel weights have been separated from alpha blend handling. Un-normalized kernels applied to images with active alpha will no longer be auto-normalized due to the effect of alpha blending. + The bug causes images using the default channel setting and having an alpha channel to automatically 'normalize' the results of a convolve during the handling of alpha blending. This probably would cause severe effects when a zero-summing kernel is being used on an image containing an active (though likely fully-opaque) alpha channel, as division by near zero weights would cause extreme color values in results. + This bug is not normally seen as convolution, which is normally applied only to fully-opaque images. And using a zero-summing kernel on an image with alpha also results in a transparent image! This is why it was not fixed up until now. +
    2012-04-08 6.7.6-6 Cristy <quetzlzacatenango@image...>

    Pixel allocation for Pango is stride*rows not stride*columns.

    A number of ImageMagick options and methods take a color as an argument. The color can then be given as a color name (there is a limited but large set of these; see below) or it can be given as a set of numbers (in decimal or hexadecimal), each corresponding to a channel in an RGB or RGBA color model. HSL, HSLA, HSB, HSBA, CMYK, or CMYKA color models may also be specified. These topics are briefly described in the sections below.

    This option is new as of ImageMagick 6.5.4-3 (and now working for Windows users in ImageMagick 6.6.0-9). It transforms an image from the normal (spatial) domain to the frequency domain. In the frequency domain, an image is represented as a superposition of complex sinusoidal waves of varying amplitudes. The image x and y coordinates are the possible frequencies along the x and y directions, respectively, and the pixel intensity values are complex numbers that correspond to the sinusoidal wave amplitudes. See for example, Fourier Transform, Discrete Fourier Transform and Fast Fourier Transform.

    A single image name is provided as output for this option. However, the output result will have two components. It is either a two-frame image or two separate images, depending upon whether the image format specified supports multi-frame images. The reason that we get a dual output result is because the frequency domain represents an image using complex numbers, which cannot be visualized directly. Therefore, the complex values are automagically separated into a two-component image representation. The first component is the magnitude of the complex number and the second is the phase of the complex number. See for example, Complex Numbers.

    - -

    $ convert image.jpg image.png

    -

    - -

    Without knowing much about the ImageMagick command line, you can probably figure out that the first command above converts an image in the JPEG format to one in the PNG format. However, very few may realize the second, more complex command, gives a flat two-dimensional label a three-dimensional look with rich textures and simulated depth:

    [ A quick word about our formatting of commands: The second example above is long enough that the command must be written across several lines, so we formatted it for clarity by inserting backslashes (\). The backslash is the Unix line continuation character. In the Windows shell, use a carat character (^) for line continuation. We use the Unix style on these web pages, as above. Sometimes, however, the lines are wrapped by your browser if the browser window is small enough, but the command lines, shown in white, are still intended to be typed as one line. Line continuation characters need not be entered. The parentheses that are escaped above using the backslash are not escaped in Windows. There are some other differences between Windows and Unix (involving quotation marks, for instance), but we'll discuss some of those issues later, as they arise. ]

    The Anatomy of the Command Line

    -
    -

    The ImageMagick command line consists of

    - -
      -
    1. one or more required input filenames.
      2. -
    2. zero, one, or more image settings.
      3. -
    3. zero, one, or more image operators.
      4. -
    4. zero, one, or more image sequence operators.
      5. -
    5. zero, one, or more image stacks.
      6. -
    6. zero or one output image filenames (required by -convert, -composite, -montage, -compare, -import, -conjure). -
      7. -
    - -

    You can find a detailed explanation of each of the constituent parts of the command line in the sections that follow.

    -
    - -

    Input Filename

    -
    - -

    ImageMagick extends the concept of an input filename to include:

    -
      -
    • filename globbing
      • -
    • an explicit image format
      • -
    • using built-in images and patterns
      • -
    • STDIN, STDOUT, and file descriptors
      • -
    • selecting certain frames from an image
      • -
    • selecting a region of an image
      • -
    • forcing an inline image resize
      • -
    • forcing an inline image crop
      • -
    • using filename references
      • -
    - -

    These extensions are explained in the next few paragraphs.

    - -

    Filename Globbing

    -
    -

    In Unix shells, certain characters such as the asterisk (*) and question mark (?) automagically cause lists of filenames to be generated based on pattern matches. This feature is known as globbing. ImageMagick supports filename globbing for systems, such as Windows, that does not natively support it. For example, suppose you want to convert 1.jpg, 2.jpg, 3.jpg, 4.jpg, and 5.jpg in your current directory to a GIF animation. You can conveniently refer to all of the JPEG files with this command: -

    - -

    $ convert *.jpg images.gif

    -
    - -

    Explicit Image Format

    -
    -

    Images are stored in a myriad of image formats including -the better known JPEG, PNG, TIFF and others. ImageMagick must know the format -of the image before it can be read and processed. Most formats have a -signature within the image that uniquely identifies the format. Failing -that, ImageMagick leverages the filename extension to determine the format. -For example, image.jpg or image.JPG tells ImageMagick -it is reading an image in the JPEG format.

    - -

    In some cases the image may not contain a signature -and/or the filename does not identify the image format. In these cases an -explicit image format must be specified. For example, suppose our image -is named image and contains raw red, green, and blue intensity -values. ImageMagick has no way to automagically determine the image format -so we explicitly set one: -

    - -

    $ convert -size 640x480 -depth 8 rgb:image image.png

    -
    - -

    Built-in Images and Patterns

    -
    -

    ImageMagick has a number of built-in images and patterns. To utilize the checkerboard pattern, for example, use: -

    - -

    $ convert -size 640x480 pattern:checkerboard checkerboard.png

    -
    - -

    STDIN, STDOUT, and file descriptors

    -
    -

    Unix and Windows permit the output of one command to be piped to the input of another. ImageMagick permits image data to be read and written from the standard streams STDIN (standard in) and STDOUT (standard out), respectively, using a pseudo-filename of -. In this example we pipe the output of - convert to the display program: -

    - -

    $ convert logo: gif:- | display gif:-

    -

    The second explicit format "gif:" is optional in the preceding example. The GIF image format has a unique signature within the image so ImageMagick's display command can readily recognize the format as GIF. The convert program also accepts STDIN as input in this way: -

    - -

    $ convert rose: gif:- | convert - -resize "200%" bigrose.jpg

    -

    Other pipes can be accessed via their file descriptors (as of version 6.4.9-3). The file descriptors 0, 1, and 2 are reserved for the standard streams STDIN, STDOUT, and STDERR, respectively, but a pipe associated with a file descriptor number N>2 can be accessed using the pseudonym fd:N. (The pseudonyms fd:0 and fd:1 can be used for STDIN and STDOUT.) The next example shows how to append image data piped from files with descriptors 3 and 4 and direct the result to the file with descriptor number 5. -

    - -

    $ convert fd:3 fd:4 -append fd:5

    -

    When needed, explicit image formats can be given as mentioned earlier, as in the following. -

    - -

    $ convert gif:fd:3 jpg:fd:4 -append tif:fd:5

    -
    - -

    Selecting Frames

    -
    -

    Some images formats contain more than one image frame. Perhaps you only want the first image, or the last, or some number of images in-between. You can specify which image frames to read by appending the image filename with the frame range enclosed in brackets. Here our image (an animated GIF) contains more than one frame but we only want the first: -

    - -

    $ convert 'images.gif[0]' image.png

    -

    [Unix shells generally interpret brackets so we enclosed the filename in quotes above. -In a Windows command shell the brackets are not interpreted but using quotes doesn't hurt. However, in most cases the roles of single-quotes and double-quotes are reversed with respect to Unix and Windows, so Windows users should usually try double-quotes where we display single-quotes, and vice versa.] -

    - -

    You can read more than one image from a sequence with a frame range. For example, you can extract the first four frames of an image sequence: -

    - -

    $ convert 'images.gif[0-3]' images.mng

    -

    Finally, you can read more than one image from a sequence, out-of-order. The next command gets the third image in the sequence, followed by the second, and then the fourth: -

    - -

    $ convert 'images.gif[3,2,4]' images.mng

    -

    Notice that in the last two commands, a single image is written. The output in this case, where the image type is MNG, is a multi-frame file because the MNG format supports multiple frames. Had the output format been JPG, which only supports single frames, the output would have consisted of separate frames. More about that below, in the section about the Output Filename. -

    -
    - -

    Selecting an Image Region

    -
    -

    Raw images are a sequence of color intensities without additional meta information such as width, height, or image signature. With raw image formats, you must specify the image width and height but you can also specify a region of the image to read. In our example, the image is in the raw 8-bit RGB format and is 6000 pixels wide and 4000 pixels high. However, we only want a region of 600 by 400 near the center of the image: -

    - -

    $ convert -size 6000x4000 -depth 8 \
    'rgb:image[600x400+1900+2900]' image.jpg

    -

    - You can get the same results with the ‑extract option: -

    - -

    $ convert -size 6000x4000 -depth 8 \
    -extract 600x400+1900+2900 rgb:image image.jpg

    -
    - -

    Inline Image Resize

    -

    It is sometimes convenient to resize an image as they are read. Suppose you have hundreds of large JPEG images you want to convert to a sequence of PNG thumbails: -

    - -

    $ convert '*.jpg' -resize 120x120 thumbnail%03d.png

    -

    Here all the images are read and subsequently -resized. It is faster and less resource intensive to resize each image it -is read: -

    - -

    $ convert '*.jpg[120x120]' thumbnail%03d.png

    -

    Inline Image Crop

    -
    -

    It is sometimes convenient to crop an image as they are read. Suppose you have hundreds of large JPEG images you want to convert to a sequence of PNG thumbails: -

    - -

    $ convert '*.jpg' -crop 120x120+10+5 thumbnail%03d.png

    -

    Here all the images are read and subsequently cropped. It is faster and less resource-intensive to crop each image as it is read: -

    - -

    $ convert '*.jpg[120x120+10+5]' thumbnail%03d.png

    -
    - -

    Filename References

    -
    -

    There are two methods to use a filename to reference other image filenames. -The first is with '@' which reads image filenames separated by white space from the specified file. Assume the file myimages.txt consists of a list of filenames, like so: -

    - -
    -  frame001.jpg
-  frame002.jpg
-  frame003.jpg
-
    - -

    We then expect this command:

    -

    $ convert @myimages.txt mymovie.gif

    to read the images frame001.jpg, frame002.jpg, and frame003.jpg and convert them to a GIF image sequence.

    -

    If the image path includes one or more spaces, enclose the path in quotes:

    -
    -  'my title.jpg'
-
    - - -

    Some ImageMagick command-line options may exceed the capabilities of -your command line processor. Windows, for example, limits command lines -to 8192 characters. If, for example, you have a draw option with polygon -points that exceed the command-line length limit, put the draw option instead -in a file and reference the file with -the @ (e.g. @mypoly.txt).

    - -

    Another method of referring to other image files is by -embedding a formatting character in the filename with a scene range. Consider -the filename image-%d.jpg[1-5]. The command

    - -

    $ convert image-%d.jpg[1-5]

    -

    causes ImageMagick to attempt to read images with these filenames: -

    - -
    -  image-1.jpg
-  image-2.jpg
-  image-3.jpg
-  image-4.jpg
-  image-5.jpg
-
    - -

    Image Setting

    -
    - -

    An image setting persists as it appears on the command line and may affect -subsequent processing such as reading an image, an image operator, or when -writing an image as appropriate. An image setting stays in effect until it -is reset or the command line terminates. The image settings include:

    - -

    -‑adjoin  • ‑affine  • ‑alpha  • ‑antialias  • ‑authenticate  • ‑background  • ‑bias  • ‑black‑point‑compensation  • ‑blue‑primary  • ‑bordercolor  • ‑caption  • ‑channel  • ‑comment  • ‑compress  • ‑debug  • ‑define  • ‑delay  • ‑density  • ‑depth  • ‑direction  • ‑display  • ‑dispose  • ‑dither  • ‑encoding  • ‑endian  • ‑extract  • ‑family  • ‑fill  • ‑filter  • ‑font  • ‑format  • ‑fuzz  • ‑geometry  • ‑gravity  • ‑green‑primary  • ‑interlace  • ‑intent  • ‑interpolate  • ‑label  • ‑limit  • ‑linewidth  • ‑log  • ‑loop  • ‑mask  • ‑mattecolor  • ‑monitor  • ‑orient  • ‑page  • ‑pointsize  • ‑preview  • ‑quality  • ‑quiet  • ‑red‑primary  • ‑region  • ‑render  • ‑repage  • ‑sampling‑factor  • ‑scene  • ‑seed  • ‑size  • ‑stretch  • ‑stroke  • ‑strokewidth  • ‑style  • ‑texture  • ‑tile  • ‑transparent‑color  • ‑treedepth  • ‑type  • ‑undercolor  • ‑units  • ‑verbose  • ‑virtual‑pixel  • ‑weight

    - -

    In this example, -channel applies to each of the images, since, as we mentioned, settings persist: -

    - -

    $ convert -channel RGB wand.png wizard.png images.png

    -
    - -

    Image Operator

    -
    - -

    An image operator differs from a setting in that it affects the image -immediately as it appears on the command line. An operator is -any command line option -not listed as a image setting -or image sequence operator. Unlike an -image setting, which persists until the command line terminates, -an operator is applied to an image and forgotten. The image operators -include:

    - -

    -‑annotate  • ‑black‑threshold  • ‑blur  • ‑border  • ‑charcoal  • ‑chop  • ‑clip  • ‑clip‑path  • ‑clip‑mask  • ‑colors  • ‑colorize  • ‑colorspace  • ‑compose  • ‑contrast  • ‑convolve  • ‑crop  • ‑cycle  • ‑despeckle  • ‑draw  • ‑edge  • ‑emboss  • ‑enhance  • ‑equalize  • ‑evaluate  • ‑extent  • ‑flip  • ‑flop  • ‑floodfill  • ‑frame  • ‑gamma  • ‑gaussian‑blur  • ‑implode  • ‑lat  • ‑level  • ‑map  • ‑median  • ‑modulate  • ‑monochrome  • ‑negate  • ‑noise  • ‑normalize  • ‑opaque  • ‑ordered‑dither  • ‑paint  • ‑posterize  • ‑raise  • ‑profile  • ‑radial‑blur  • ‑raise  • ‑random‑threshold  • ‑resample  • ‑resize  • ‑roll  • ‑rotate  • ‑sample  • ‑scale  • ‑sepia‑tone  • ‑segment  • ‑shade  • ‑shadow  • ‑sharpen  • ‑shave  • ‑shear  • ‑sigmoidal‑contrast  • ‑solarize  • ‑splice  • ‑spread  • ‑strip  • ‑swirl  • ‑threshold  • ‑transparent  • ‑thumbnail  • ‑tint  • ‑transform  • ‑trim  • ‑unsharp  • ‑version  • ‑wave  • ‑white‑point  • ‑white‑threshold

    - -

    In this example, -negate negates the wand image but not the wizard:

    - -

    $ convert wand.png -negate wizard.png images.png

    - -

    Image Sequence Operator

    -
    - -

    An image sequence operator differs from a setting in that it affects an -image sequence immediately as it appears on the command line. Choose from -these image sequence operators:

    - -

    -‑append  • ‑affinity  • ‑average  • ‑clut  • ‑coalesce  • ‑combine  • ‑composite  • ‑crop  • ‑debug  • ‑deconstruct  • ‑delete  • ‑evaluate‑seqence  • ‑fft  • ‑flatten  • ‑fx  • ‑hald‑clut  • ‑ift  • ‑identify  • ‑insert  • ‑layers  • ‑limit  • ‑map  • ‑maximum  • ‑minimum  • ‑morph  • ‑mosaic  • ‑optimize  • ‑print  • ‑process  • ‑quiet  • ‑separate  • ‑swap  • ‑write

    Image Geometry

    -
    - -

    Many command-line options take a geometry argument -to specify such things as the desired width and height of an image and other -dimensional quantities. Because users want so many variations on the resulting -dimensions, sizes, and positions of images (and because ImageMagick wants to -provide them), the geometry argument can take many -forms. We describe many of these in this section.

    - -

    The image options and settings that take some form of -a geometry argument include the following. -Keep in mind that some of these parse their arguments in slightly -different ways. See the documentation for the individual option or -setting for more specifics.

    - -

    -‑adaptive‑resize  • ‑border  • ‑borderwidth  • ‑chop  • ‑crop  • ‑density  • ‑extent  • ‑extract  • ‑frame  • ‑geometry  • ‑iconGeometry  • ‑liquid‑rescale  • ‑page  • ‑region  • ‑repage  • ‑resize  • ‑sample  • ‑scale  • ‑shave  • ‑splice  • ‑thumbnail  • ‑window

    - -

    The geometry argument might take any of the forms listed in the table below. These will described in more detail in the subsections following the table. The usual form is size[offset], meaning size is required and offset is optional. Occasionally, [size]offset is possible. In no cases are spaces permitted within the geometry argument.

    - - -

    Basic adjustments to width and height; the operators %, ^, and !

    -
    -

    Here, just below, are a few simple examples of geometry, showing how it might be used as an argument to the ‑resize option. We'll use the internal image logo: for our input image. - -This fine image is 640 pixels wide and 480 pixels high. We say its dimensions are 640x480. When we give dimensions of an image, the width (the horizontal dimension) always precedes the height (the vertical dimension). This will be true when we speak of coordinates or offsets into an image, which will always be x–value followed by y. Just think of your high school algebra classes and the xy–plane. (Well, almost: our y–axis will always go downward!) -

    - -

    $ convert logo: -resize '200%' bigWiz.png

    -

    $ convert logo: -resize '200x50%' longShortWiz.png

    -

    $ convert logo: -resize '100x200' notThinWiz.png

    -

    $ convert logo: -resize '100x200^' biggerNotThinWiz.png

    -

    $ convert logo: -resize '100x200!' dochThinWiz.png

    - -

    The first of the four commands is simple—it stretches both the width and height of the input image by 200% in each direction; it magnifies the whole thing by a factor of two. The second command specifies different percentages for each direction, stretching the width to 200% and squashing the height to 50%. The resulting image (in this example) has dimensions 1280x240. Notice that the percent symbol needn't be repeated; the following are equivalent: 200x50%, 200%x50, 200%x50%. -

    - -

    By default, the width and height given in a geometry argument are maximum values unless a percentage is specified. That is, the image is expanded or contracted to fit the specified width and height value while maintaining the aspect ratio (the ratio of its height to its width) of the image. For instance, the third command above "tries" to set the dimensions to 100x200. Imagine gradually shrinking the original image (which is 640x480), keeping is aspect ratio constant, until it just fits into a 100x200 rectangle. Since the image is longer than it is tall, it will fit when its width shrinks to 100 pixels. To preserve the aspect ratio, the height will therefore have to be (480/640)×100 pixels=75 pixels, so the final dimensions will be 100x75.

    - -

    Notice that in the previous example, at least one of the specified dimensions will be attained (in this case, the width, 100 pixels). The resulting image fits snugly within the original. One can do just the opposite of this by invoking the ^ operator, as in the fourth example above. In that case, when 100x200^ is given as the argument, again at least one of the dimensions will be attained, but in this case the resulting image can snugly contain the original. Here the geometry argument gives minimum values. In our example, the height will become 200 and the width will be scaled to preserve the aspect ratio, becoming (640/480)×200 pixels=267 pixels. With the ^ operator, one of those dimensions will match the requested size, but the image will likely overflow the dimensions requested to preserve its aspect ratio. (The ^ feature is new as of IM 6.3.8-2.)

    - -

    We see that ImageMagick is very good about preserving aspect ratios of images, to prevent distortion of your favorite photos and images. But you might really want the dimensions to be 100x200, thereby stretching the image. In this case just tell ImageMagick you really mean it (!) by appending an exclamation operator to the geometry. This will force the image size to exactly what you specify. So, for example, if you specify 100x200! the dimensions will become exactly 100x200 (giving a small, vertically elongated wizard).

    -
    - -

    Bounding the width, height, and area; the operators >, <, and @

    -
    -

    -Here are a few more examples: -

    - -

    $ convert logo: -resize '100' wiz1.png

    -

    $ convert logo: -resize 'x200' wiz2.png

    -

    $ convert logo: -resize '100x200>' wiz3.png

    -

    $ convert logo: -resize '100x200<' wiz4.png

    -

    If only one dimension is given it is taken to be the width. When only the width is specified, as in the first example above, the width is accepted as given and the height is chosen to maintain the aspect ratio of the input image. Similarly, if only the height is specified, as in the second example above, the height is accepted and the width is chosen to maintain the aspect ratio.

    - - -

    Use > to change the dimensions of the image only if the original width or height is exeeded by one of the geometry specifications. Use < to resize the image only if the original dimensions are more than the geometry specifications. In either case, if a change is made, the result is as if the > or > operator was not present. So, in the third example above, we specified 100x200> and the original image size is 640x480, so the image size is reduced as if we had specified 100x200. However, in the fourth example above, there will be no change to its size.

    - -

    Finally, use @ to specify the maximum area in pixels of an image, again while attempting to preserve aspect ratio. (Pixels take only integer values, so some approximation is always at work.) In the following example, an area of 10000 pixels is requested. The resulting file has dimensions 115x86, which has 9890 pixels.

    - -

    $ convert logo: -resize '@10000' wiz10000.png

    -

    Another word about the quotation marks: In all the examples above and below, we have enclosed the geometry arguments within quotation marks. Doing so is optional in many cases, but not always. We must enclose the geometry specifications in quotation marks when using < or > to prevent these characters from being interpreted by the shell as file redirection. On Windows systems, the carat ^  needs to be within quotes, else it is ignored. To be safe, one should probably maintain a habit of enclosing all geometry arguments in quotes, as we have here. -

    -
    - -

    Offsets in geometry

    -
    -

    -Here are some examples to illustrate the use of offsets in geometry arguments. One typical use of offsets is in conjunction with the -‑region option. This option allows many other options to modify the pixels within a specified rectangular subregion of an image. As such, it needs to be given the width and height of that region, and also an offset into the image, which is a pair of coordinates that indicate the location of the region within the larger image. Below, in the first example, we specify a region of size 100x200 to be located at the xy–coordinates x=10, y=20. Let's use the usual algebraic notation (x,y)=(10,20), for convenience. -

    - -

    $ convert logo: -region '100x200+10+20' -negate wizNeg1.png

    -

    $ convert logo: -region '100x200-10+20' -negate wizNeg2.png

    -

    $ convert logo: -gravity center -region '100x200-10+20' \
    -negate wizNeg3.png

    - -

    Note that offsets always require +/− signs. The offset is not actually a true location within the image; its coordinates must be added to some other location. Let's refer to that as the current location. In the first two examples above, though, that location is the upper-left hand corner of the image, which has coordinates (0,0). (That is the default situation when there are no other directives given to change it.) The first example above puts the 100x200 rectangle's own upper-left corner at (10,20).

    - -

    A negative offset can make sense in many cases. In the second example above, the offset is (-10,20), specified by -10+20. In that case, only the portion of the (virtual) rectangle obtained that lies within the image can be negated; here it is equivalent to specifying the geometry as 90x200+0+20.

    - -

    In the third example above, the ‑gravity setting precedes the others and sets the current location within the image at the very center of the image. In this case that is at pixel (320,240), since the size of the image is 640x480. This means that the offsets apply to that location, which thereby gets moved, in this case, to (320-10,240+20)=(310,260). But the 100x200 region itself is affected by the ‑gravity setting, so instead of affecting its upper-left corner, the region's own center (at (+50,+100) within it) is determined. Therefore the center of the 100x200 rectangle is moved to (310,260). The negated rectangle's upper-left corner is now at (310-50,260-100)=(260,160). -

    - - -

    Image Stack

    -
    - -

    In school, your teacher probably permitted you to work on problems on a scrap of paper and then copy the results to your test paper. An image stack is similar. It permits you to work on an image or image sequence in isolation and subsequently introduce the results back into the command line. The image stack is delineated with parenthesis. Image operators only affect images in the current stack. For example, we can limit the image rotation to just the wizard image like this:

    - -

    $ convert wand.gif \( wizard.gif -rotate 30 \) +append images.gif

    - -

    Notice again that the parentheses are escaped by preceding them with -backslashes. This is required under Unix, where parentheses are special -shell characters. The backslash tells the shell not to interpret -these characters, but to pass them directly to the command being executed. Do -not escape the parentheses under Windows. Each parenthesis (or escaped -parenthesis) must have spaces on either side, as in the example shown -above.

    - -

    In addition to the image operators already discussed, the following image operators are most useful when processing images in an image stack:

    - -

    - • -‑clone  • ‑delete  • ‑insert  • ‑swap  • -

    - -

    The arguments to these operators are indexes into the image sequence by number, starting with zero, for the first image, and so on. However if you give a negative index, the images are indexed from the end (last image added). That is, an index of -1 is the last image in the current image sequence, -2 gives the second-to-last, and so on.

    - -
    - -

    Output Filename

    -
    - -

    ImageMagick extends the concept of an output filename to include:

    - -
      -
    1. an explicit image format
      2. -
    2. write to standard out
      3. -
    3. filename references
      4. -
    - -

    Each of these extensions are explained in the next few paragraphs.

    - -

    Explicit Image Format

    -
    -

    Images can be stored in a mryiad of image formats including the better known JPEG, PNG, TIFF and others. ImageMagick must know the desired format of the image before it is written. ImageMagick leverages the filename extension to determine the format. For example, image.jpg tells ImageMagick to write the image in the JPEG format. In some cases the filename does not identify the image format. In these cases, the image is written in the format it was originally read unless an explicit image format is specified. For example, suppose we want to write our image to a filename of image in the raw red, green, and blue intensity format: -

    - -

    $ convert image.jpg rgb:image

    -
    - -

    Standard Out

    -
    -

    Unix permits the output of one command to be piped to another. ImageMagick permits piping one command to another with a filename of -. In this example we pipe the output of convert to the display program: -

    - -

    $ convert logo: gif:- | display gif:-

    -

    Here the explicit format is optional. The GIF image format has a signature that uniquely identifies it so ImageMagick can readily recognize the format as GIF. -

    -
    - -

    Filename References

    -
    -

    Optionally, use an embedded formatting character to write a sequential image list. Suppose our output filename is image-%d.jpg and our image list includes 3 images. You can expect these images files to be written: -

    - -
    -  image-0.jpg
-  image-1.jpg
-  image-2.jpg
-
    - -

    Or retrieve image properties to modify the image filename. For example, the command -

    - -

    $ convert rose: -set filename:area '%wx%h' \
    'rose-%[filename:area].png'

    -

    writes an image with this filename: -

    - -
    -  rose-70x46.png
-
    - -

    Finally to convert multiple JPEG images to individual PDF pages, use:

    - -
    -  convert *.jpg +adjoin page-%d.pdf
-
    - -
    - -
    - +

    ImageMagick Command-line Processing

    [The Anatomy of the Command Line • Input Filename • Image Setting • Image Operator • Image Sequence Operator • Image Geometry • Image Stack • Output Filename]

    The ImageMagick command line can be as simple as this.

    $ convert image.jpg image.png

    Or it can be very complex, as in the following.

    $ convert label.gif +matte \
    \( +clone -shade 110x90 -normalize -negate +clone -compose Plus -composite \) \
    \( -clone 0 -shade 110x50 -normalize -channel BG -fx 0 +channel -matte \) \
    -delete 0 +swap -compose Multiply -composite button.gif

    Without knowing much about the ImageMagick command line, you can probably figure out that the first command above converts an image in the JPEG format to one in the PNG format. However, very few may realize the second, more complex command, gives a flat two-dimensional label a three-dimensional look with rich textures and simulated depth:

    label ==> button

    [ A quick word about our formatting of commands: The second example above is long enough that the command must be written across several lines, so we formatted it for clarity by inserting backslashes (\). The backslash is the Unix line continuation character. In the Windows shell, use a carat character (^) for line continuation. We use the Unix style on these web pages, as above. Sometimes, however, the lines are wrapped by your browser if the browser window is small enough, but the command lines, shown in white, are still intended to be typed as one line. Line continuation characters need not be entered. The parentheses that are escaped above using the backslash are not escaped in Windows. There are some other differences between Windows and Unix (involving quotation marks, for instance), but we'll discuss some of those issues later, as they arise. ]

    Here we show percent completion of a task as a shaded cylinder:

    Shaded Cylinder

    Given the complexity of the rendering, you might be surprised it is accomplished by a single command-line:

    convert -size 320x90 canvas:none -stroke snow4 -size 1x90 -tile gradient:white-snow4 \
  -draw 'roundrectangle 16, 5, 304, 85 20,40' +tile -fill snow \
  -draw 'roundrectangle 264, 5, 304, 85  20,40' -tile gradient:chartreuse-green \
  -draw 'roundrectangle 16,  5, 180, 85  20,40' -tile gradient:chartreuse1-chartreuse3 \
  -draw 'roundrectangle 140, 5, 180, 85  20,40' +tile -fill none \
  -draw 'roundrectangle 264, 5, 304, 85 20,40' -strokewidth 2 \
  -draw 'roundrectangle 16, 5, 304, 85 20,40' \( +clone -background snow4 \

    In the next sections we dissect the anatomy of the ImageMagick command line. Hopefully, after carefully reading and better understanding how the command line works, you should be able to accomplish complex image-processing tasks without resorting to the sometimes daunting program interfaces.

    See Examples of ImageMagick Usage for additional help when using ImageMagick from the command-line.

    The Anatomy of the Command Line

    The ImageMagick command line consists of

    1. one or more required input filenames.
    2. zero, one, or more image settings.
    3. zero, one, or more image operators.
    4. zero, one, or more image sequence operators.
    5. zero, one, or more image stacks.
    6. zero or one output image filenames (required by convert, composite, montage, compare, import, conjure).

    You can find a detailed explanation of each of the constituent parts of the command line in the sections that follow.

    Input Filename

    ImageMagick extends the concept of an input filename to include:

    • filename globbing
    • an explicit image format
    • using built-in images and patterns
    • STDIN, STDOUT, and file descriptors
    • selecting certain frames from an image
    • selecting a region of an image
    • forcing an inline image resize
    • forcing an inline image crop
    • using filename references

    These extensions are explained in the next few paragraphs.

    Filename Globbing

    In Unix shells, certain characters such as the asterisk (*) and question mark (?) automagically cause lists of filenames to be generated based on pattern matches. This feature is known as globbing. ImageMagick supports filename globbing for systems, such as Windows, that does not natively support it. For example, suppose you want to convert 1.jpg, 2.jpg, 3.jpg, 4.jpg, and 5.jpg in your current directory to a GIF animation. You can conveniently refer to all of the JPEG files with this command:

    $ convert *.jpg images.gif

    Explicit Image Format

    Images are stored in a myriad of image formats including the better known JPEG, PNG, TIFF and others. ImageMagick must know the format of the image before it can be read and processed. Most formats have a signature within the image that uniquely identifies the format. Failing that, ImageMagick leverages the filename extension to determine the format. For example, image.jpg or image.JPG tells ImageMagick it is reading an image in the JPEG format.

    In some cases the image may not contain a signature and/or the filename does not identify the image format. In these cases an explicit image format must be specified. For example, suppose our image is named image and contains raw red, green, and blue intensity values. ImageMagick has no way to automagically determine the image format so we explicitly set one:

    $ convert -size 640x480 -depth 8 rgb:image image.png

    Built-in Images and Patterns

    ImageMagick has a number of built-in images and patterns. To utilize the checkerboard pattern, for example, use:

    $ convert -size 640x480 pattern:checkerboard checkerboard.png

    STDIN, STDOUT, and file descriptors

    Unix and Windows permit the output of one command to be piped to the input of another. ImageMagick permits image data to be read and written from the standard streams STDIN (standard in) and STDOUT (standard out), respectively, using a pseudo-filename of -. In this example we pipe the output of convert to the display program:

    $ convert logo: gif:- | display gif:-

    The second explicit format "gif:" is optional in the preceding example. The GIF image format has a unique signature within the image so ImageMagick's display command can readily recognize the format as GIF. The convert program also accepts STDIN as input in this way:

    $ convert rose: gif:- | convert - -resize "200%" bigrose.jpg

    Other pipes can be accessed via their file descriptors (as of version 6.4.9-3). The file descriptors 0, 1, and 2 are reserved for the standard streams STDIN, STDOUT, and STDERR, respectively, but a pipe associated with a file descriptor number N>2 can be accessed using the pseudonym fd:N. (The pseudonyms fd:0 and fd:1 can be used for STDIN and STDOUT.) The next example shows how to append image data piped from files with descriptors 3 and 4 and direct the result to the file with descriptor number 5.

    $ convert fd:3 fd:4 -append fd:5

    When needed, explicit image formats can be given as mentioned earlier, as in the following.

    $ convert gif:fd:3 jpg:fd:4 -append tif:fd:5

    Selecting Frames

    Some images formats contain more than one image frame. Perhaps you only want the first image, or the last, or some number of images in-between. You can specify which image frames to read by appending the image filename with the frame range enclosed in brackets. Here our image (an animated GIF) contains more than one frame but we only want the first:

    $ convert 'images.gif[0]' image.png

    [Unix shells generally interpret brackets so we enclosed the filename in quotes above. In a Windows command shell the brackets are not interpreted but using quotes doesn't hurt. However, in most cases the roles of single-quotes and double-quotes are reversed with respect to Unix and Windows, so Windows users should usually try double-quotes where we display single-quotes, and vice versa.]

    You can read more than one image from a sequence with a frame range. For example, you can extract the first four frames of an image sequence:

    $ convert 'images.gif[0-3]' images.mng

    Finally, you can read more than one image from a sequence, out-of-order. The next command gets the third image in the sequence, followed by the second, and then the fourth:

    $ convert 'images.gif[3,2,4]' images.mng

    Notice that in the last two commands, a single image is written. The output in this case, where the image type is MNG, is a multi-frame file because the MNG format supports multiple frames. Had the output format been JPG, which only supports single frames, the output would have consisted of separate frames. More about that below, in the section about the Output Filename.

    Selecting an Image Region

    Raw images are a sequence of color intensities without additional meta information such as width, height, or image signature. With raw image formats, you must specify the image width and height but you can also specify a region of the image to read. In our example, the image is in the raw 8-bit RGB format and is 6000 pixels wide and 4000 pixels high. However, we only want a region of 600 by 400 near the center of the image:

    $ convert -size 6000x4000 -depth 8 \
    'rgb:image[600x400+1900+2900]' image.jpg

    You can get the same results with the ‑extract option:

    $ convert -size 6000x4000 -depth 8 \
    -extract 600x400+1900+2900 rgb:image image.jpg

    Inline Image Resize

    It is sometimes convenient to resize an image as they are read. Suppose you have hundreds of large JPEG images you want to convert to a sequence of PNG thumbails:

    $ convert '*.jpg' -resize 120x120 thumbnail%03d.png

    Here all the images are read and subsequently resized. It is faster and less resource intensive to resize each image it is read:

    $ convert '*.jpg[120x120]' thumbnail%03d.png

    Inline Image Crop

    It is sometimes convenient to crop an image as they are read. Suppose you have hundreds of large JPEG images you want to convert to a sequence of PNG thumbails:

    $ convert '*.jpg' -crop 120x120+10+5 thumbnail%03d.png

    Here all the images are read and subsequently cropped. It is faster and less resource-intensive to crop each image as it is read:

    $ convert '*.jpg[120x120+10+5]' thumbnail%03d.png

    Filename References

    There are two methods to use a filename to reference other image filenames. The first is with '@' which reads image filenames separated by white space from the specified file. Assume the file myimages.txt consists of a list of filenames, like so: 

      frame001.jpg
  frame002.jpg
  frame003.jpg

    We then expect this command:

    $ convert @myimages.txt mymovie.gif

    to read the images frame001.jpg, frame002.jpg, and frame003.jpg and convert them to a GIF image sequence.

    If the image path includes one or more spaces, enclose the path in quotes:

      'my title.jpg'

    Some ImageMagick command-line options may exceed the capabilities of your command line processor. Windows, for example, limits command lines to 8192 characters. If, for example, you have a draw option with polygon points that exceed the command-line length limit, put the draw option instead in a file and reference the file with the @ (e.g. @mypoly.txt).

    Another method of referring to other image files is by embedding a formatting character in the filename with a scene range. Consider the filename image-%d.jpg[1-5]. The command

    $ convert image-%d.jpg[1-5]

    causes ImageMagick to attempt to read images with these filenames: 

      image-1.jpg
  image-2.jpg
  image-3.jpg
  image-4.jpg
  image-5.jpg

    Image Setting

    An image setting persists as it appears on the command line and may affect subsequent processing such as reading an image, an image operator, or when writing an image as appropriate. An image setting stays in effect until it is reset or the command line terminates. The image settings include:

    ‑adjoin  • ‑affine  • ‑alpha  • ‑antialias  • ‑authenticate  • ‑background  • ‑bias  • ‑black‑point‑compensation  • ‑blue‑primary  • ‑bordercolor  • ‑caption  • ‑channel  • ‑comment  • ‑compress  • ‑debug  • ‑define  • ‑delay  • ‑density  • ‑depth  • ‑direction  • ‑display  • ‑dispose  • ‑dither  • ‑encoding  • ‑endian  • ‑extract  • ‑family  • ‑fill  • ‑filter  • ‑font  • ‑format  • ‑fuzz  • ‑geometry  • ‑gravity  • ‑green‑primary  • ‑interlace  • ‑intent  • ‑interpolate  • ‑label  • ‑limit  • ‑linewidth  • ‑log  • ‑loop  • ‑mask  • ‑mattecolor  • ‑monitor  • ‑orient  • ‑page  • ‑pointsize  • ‑preview  • ‑quality  • ‑quiet  • ‑red‑primary  • ‑region  • ‑render  • ‑repage  • ‑sampling‑factor  • ‑scene  • ‑seed  • ‑size  • ‑stretch  • ‑stroke  • ‑strokewidth  • ‑style  • ‑texture  • ‑tile  • ‑transparent‑color  • ‑treedepth  • ‑type  • ‑undercolor  • ‑units  • ‑verbose  • ‑virtual‑pixel  • ‑weight

    In this example, -channel applies to each of the images, since, as we mentioned, settings persist:

    $ convert -channel RGB wand.png wizard.png images.png

    Image Operator

    An image operator differs from a setting in that it affects the image immediately as it appears on the command line. An operator is any command line option not listed as a image setting or image sequence operator. Unlike an image setting, which persists until the command line terminates, an operator is applied to an image and forgotten. The image operators include:

    ‑annotate  • ‑black‑threshold  • ‑blur  • ‑border  • ‑charcoal  • ‑chop  • ‑clip  • ‑clip‑path  • ‑clip‑mask  • ‑colors  • ‑colorize  • ‑colorspace  • ‑compose  • ‑contrast  • ‑convolve  • ‑crop  • ‑cycle  • ‑despeckle  • ‑draw  • ‑edge  • ‑emboss  • ‑enhance  • ‑equalize  • ‑evaluate  • ‑extent  • ‑flip  • ‑flop  • ‑floodfill  • ‑frame  • ‑gamma  • ‑gaussian‑blur  • ‑implode  • ‑lat  • ‑level  • ‑map  • ‑median  • ‑modulate  • ‑monochrome  • ‑negate  • ‑noise  • ‑normalize  • ‑opaque  • ‑ordered‑dither  • ‑paint  • ‑posterize  • ‑raise  • ‑profile  • ‑radial‑blur  • ‑raise  • ‑random‑threshold  • ‑resample  • ‑resize  • ‑roll  • ‑rotate  • ‑sample  • ‑scale  • ‑sepia‑tone  • ‑segment  • ‑shade  • ‑shadow  • ‑sharpen  • ‑shave  • ‑shear  • ‑sigmoidal‑contrast  • ‑solarize  • ‑splice  • ‑spread  • ‑strip  • ‑swirl  • ‑threshold  • ‑transparent  • ‑thumbnail  • ‑tint  • ‑transform  • ‑trim  • ‑unsharp  • ‑version  • ‑wave  • ‑white‑point  • ‑white‑threshold

    In this example, -negate negates the wand image but not the wizard:

    $ convert wand.png -negate wizard.png images.png

    Image Sequence Operator

    An image sequence operator differs from a setting in that it affects an image sequence immediately as it appears on the command line. Choose from these image sequence operators:

    ‑append  • ‑affinity  • ‑average  • ‑clut  • ‑coalesce  • ‑combine  • ‑composite  • ‑crop  • ‑debug  • ‑deconstruct  • ‑delete  • ‑evaluate‑seqence  • ‑fft  • ‑flatten  • ‑fx  • ‑hald‑clut  • ‑ift  • ‑identify  • ‑insert  • ‑layers  • ‑limit  • ‑map  • ‑maximum  • ‑minimum  • ‑morph  • ‑mosaic  • ‑optimize  • ‑print  • ‑process  • ‑quiet  • ‑separate  • ‑swap  • ‑write

    Image Geometry

    Many command-line options take a geometry argument to specify such things as the desired width and height of an image and other dimensional quantities. Because users want so many variations on the resulting dimensions, sizes, and positions of images (and because ImageMagick wants to provide them), the geometry argument can take many forms. We describe many of these in this section.

    The image options and settings that take some form of a geometry argument include the following. Keep in mind that some of these parse their arguments in slightly different ways. See the documentation for the individual option or setting for more specifics.

    ‑adaptive‑resize  • ‑border  • ‑borderwidth  • ‑chop  • ‑crop  • ‑density  • ‑extent  • ‑extract  • ‑frame  • ‑geometry  • ‑iconGeometry  • ‑liquid‑rescale  • ‑page  • ‑region  • ‑repage  • ‑resize  • ‑sample  • ‑scale  • ‑shave  • ‑splice  • ‑thumbnail  • ‑window

    The geometry argument might take any of the forms listed in the table below. These will described in more detail in the subsections following the table. The usual form is size[offset], meaning size is required and offset is optional. Occasionally, [size]offset is possible. In no cases are spaces permitted within the geometry argument.

    size General description (actual behavior can vary for different options and settings)
    scale% Height and width both scaled by specified percentage.
    scale-x%xscale-y% Height and width individually scaled by specified percentages. (Only one % symbol needed.)
    width Width given, height automagically selected to preserve aspect ratio.
    xheight Height given, width automagically selected to preserve aspect ratio.
    widthxheight Maximum values of height and width given, aspect ratio preserved.
    widthxheight^ Minimum values of width and height given, aspect ratio preserved.
    widthxheight! Width and height emphatically given, original aspect ratio ignored.
    widthxheight> Shrinks images with dimension(s) larger than the corresponding width and/or height dimension(s).
    widthxheight< Enlarges images with dimension(s) smaller than the corresponding width and/or height dimension(s).
    area@ Resize image to have specified area in pixels. Aspect ratio is preserved.
    {size}{offset} Specifying the offset (default is +0+0). Below, {size} refers to any of the forms above.
    {size}{+-}x{+-}y Horizontal and vertical offsets x and y, specified in pixels. Signs are required for both. Offsets are affected by ‑gravity setting. Offsets are not affected by % or other size operators.

    Basic adjustments to width and height; the operators %, ^, and !

    Here, just below, are a few simple examples of geometry, showing how it might be used as an argument to the ‑resize option. We'll use the internal image logo: for our input image. This fine image is 640 pixels wide and 480 pixels high. We say its dimensions are 640x480. When we give dimensions of an image, the width (the horizontal dimension) always precedes the height (the vertical dimension). This will be true when we speak of coordinates or offsets into an image, which will always be x–value followed by y. Just think of your high school algebra classes and the xy–plane. (Well, almost: our y–axis will always go downward!)

    $ convert logo: -resize '200%' bigWiz.png

    $ convert logo: -resize '200x50%' longShortWiz.png

    $ convert logo: -resize '100x200' notThinWiz.png

    $ convert logo: -resize '100x200^' biggerNotThinWiz.png

    $ convert logo: -resize '100x200!' dochThinWiz.png

    The first of the four commands is simple—it stretches both the width and height of the input image by 200% in each direction; it magnifies the whole thing by a factor of two. The second command specifies different percentages for each direction, stretching the width to 200% and squashing the height to 50%. The resulting image (in this example) has dimensions 1280x240. Notice that the percent symbol needn't be repeated; the following are equivalent: 200x50%, 200%x50, 200%x50%.

    By default, the width and height given in a geometry argument are maximum values unless a percentage is specified. That is, the image is expanded or contracted to fit the specified width and height value while maintaining the aspect ratio (the ratio of its height to its width) of the image. For instance, the third command above "tries" to set the dimensions to 100x200. Imagine gradually shrinking the original image (which is 640x480), keeping is aspect ratio constant, until it just fits into a 100x200 rectangle. Since the image is longer than it is tall, it will fit when its width shrinks to 100 pixels. To preserve the aspect ratio, the height will therefore have to be (480/640)×100 pixels=75 pixels, so the final dimensions will be 100x75.

    Notice that in the previous example, at least one of the specified dimensions will be attained (in this case, the width, 100 pixels). The resulting image fits snugly within the original. One can do just the opposite of this by invoking the ^ operator, as in the fourth example above. In that case, when 100x200^ is given as the argument, again at least one of the dimensions will be attained, but in this case the resulting image can snugly contain the original. Here the geometry argument gives minimum values. In our example, the height will become 200 and the width will be scaled to preserve the aspect ratio, becoming (640/480)×200 pixels=267 pixels. With the ^ operator, one of those dimensions will match the requested size, but the image will likely overflow the dimensions requested to preserve its aspect ratio. (The ^ feature is new as of IM 6.3.8-2.)

    We see that ImageMagick is very good about preserving aspect ratios of images, to prevent distortion of your favorite photos and images. But you might really want the dimensions to be 100x200, thereby stretching the image. In this case just tell ImageMagick you really mean it (!) by appending an exclamation operator to the geometry. This will force the image size to exactly what you specify. So, for example, if you specify 100x200! the dimensions will become exactly 100x200 (giving a small, vertically elongated wizard).

    Bounding the width, height, and area; the operators >, <, and @

    Here are a few more examples:

    $ convert logo: -resize '100' wiz1.png

    $ convert logo: -resize 'x200' wiz2.png

    $ convert logo: -resize '100x200>' wiz3.png

    $ convert logo: -resize '100x200<' wiz4.png

    If only one dimension is given it is taken to be the width. When only the width is specified, as in the first example above, the width is accepted as given and the height is chosen to maintain the aspect ratio of the input image. Similarly, if only the height is specified, as in the second example above, the height is accepted and the width is chosen to maintain the aspect ratio.

    Use > to change the dimensions of the image only if the original width or height is exeeded by one of the geometry specifications. Use < to resize the image only if the original dimensions are more than the geometry specifications. In either case, if a change is made, the result is as if the > or > operator was not present. So, in the third example above, we specified 100x200> and the original image size is 640x480, so the image size is reduced as if we had specified 100x200. However, in the fourth example above, there will be no change to its size.

    Finally, use @ to specify the maximum area in pixels of an image, again while attempting to preserve aspect ratio. (Pixels take only integer values, so some approximation is always at work.) In the following example, an area of 10000 pixels is requested. The resulting file has dimensions 115x86, which has 9890 pixels.

    $ convert logo: -resize '@10000' wiz10000.png

    Another word about the quotation marks: In all the examples above and below, we have enclosed the geometry arguments within quotation marks. Doing so is optional in many cases, but not always. We must enclose the geometry specifications in quotation marks when using < or > to prevent these characters from being interpreted by the shell as file redirection. On Windows systems, the carat ^  needs to be within quotes, else it is ignored. To be safe, one should probably maintain a habit of enclosing all geometry arguments in quotes, as we have here.

    Offsets in geometry

    Here are some examples to illustrate the use of offsets in geometry arguments. One typical use of offsets is in conjunction with the ‑region option. This option allows many other options to modify the pixels within a specified rectangular subregion of an image. As such, it needs to be given the width and height of that region, and also an offset into the image, which is a pair of coordinates that indicate the location of the region within the larger image. Below, in the first example, we specify a region of size 100x200 to be located at the xy–coordinates x=10, y=20. Let's use the usual algebraic notation (x,y)=(10,20), for convenience.

    $ convert logo: -region '100x200+10+20' -negate wizNeg1.png

    $ convert logo: -region '100x200-10+20' -negate wizNeg2.png

    $ convert logo: -gravity center -region '100x200-10+20' \
    -negate wizNeg3.png

    Note that offsets always require +/− signs. The offset is not actually a true location within the image; its coordinates must be added to some other location. Let's refer to that as the current location. In the first two examples above, though, that location is the upper-left hand corner of the image, which has coordinates (0,0). (That is the default situation when there are no other directives given to change it.) The first example above puts the 100x200 rectangle's own upper-left corner at (10,20).

    A negative offset can make sense in many cases. In the second example above, the offset is (-10,20), specified by -10+20. In that case, only the portion of the (virtual) rectangle obtained that lies within the image can be negated; here it is equivalent to specifying the geometry as 90x200+0+20.

    In the third example above, the ‑gravity setting precedes the others and sets the current location within the image at the very center of the image. In this case that is at pixel (320,240), since the size of the image is 640x480. This means that the offsets apply to that location, which thereby gets moved, in this case, to (320-10,240+20)=(310,260). But the 100x200 region itself is affected by the ‑gravity setting, so instead of affecting its upper-left corner, the region's own center (at (+50,+100) within it) is determined. Therefore the center of the 100x200 rectangle is moved to (310,260). The negated rectangle's upper-left corner is now at (310-50,260-100)=(260,160).

    Image Stack

    In school, your teacher probably permitted you to work on problems on a scrap of paper and then copy the results to your test paper. An image stack is similar. It permits you to work on an image or image sequence in isolation and subsequently introduce the results back into the command line. The image stack is delineated with parenthesis. Image operators only affect images in the current stack. For example, we can limit the image rotation to just the wizard image like this:

    $ convert wand.gif \( wizard.gif -rotate 30 \) +append images.gif

    Notice again that the parentheses are escaped by preceding them with backslashes. This is required under Unix, where parentheses are special shell characters. The backslash tells the shell not to interpret these characters, but to pass them directly to the command being executed. Do not escape the parentheses under Windows. Each parenthesis (or escaped parenthesis) must have spaces on either side, as in the example shown above.

    In addition to the image operators already discussed, the following image operators are most useful when processing images in an image stack:

     • ‑clone  • ‑delete  • ‑insert  • ‑swap  •

    The arguments to these operators are indexes into the image sequence by number, starting with zero, for the first image, and so on. However if you give a negative index, the images are indexed from the end (last image added). That is, an index of -1 is the last image in the current image sequence, -2 gives the second-to-last, and so on.

    Output Filename

    ImageMagick extends the concept of an output filename to include:

    1. an explicit image format
    2. write to standard out
    3. filename references

    Each of these extensions are explained in the next few paragraphs.

    Explicit Image Format

    Images can be stored in a mryiad of image formats including the better known JPEG, PNG, TIFF and others. ImageMagick must know the desired format of the image before it is written. ImageMagick leverages the filename extension to determine the format. For example, image.jpg tells ImageMagick to write the image in the JPEG format. In some cases the filename does not identify the image format. In these cases, the image is written in the format it was originally read unless an explicit image format is specified. For example, suppose we want to write our image to a filename of image in the raw red, green, and blue intensity format:

    $ convert image.jpg rgb:image

    Standard Out

    Unix permits the output of one command to be piped to another. ImageMagick permits piping one command to another with a filename of -. In this example we pipe the output of convert to the display program:

    $ convert logo: gif:- | display gif:-

    Here the explicit format is optional. The GIF image format has a signature that uniquely identifies it so ImageMagick can readily recognize the format as GIF.

    Filename References

    Optionally, use an embedded formatting character to write a sequential image list. Suppose our output filename is image-%d.jpg and our image list includes 3 images. You can expect these images files to be written: 

      image-0.jpg
  image-1.jpg
  image-2.jpg

    Or retrieve image properties to modify the image filename. For example, the command

    $ convert rose: -set filename:area '%wx%h' \
    'rose-%[filename:area].png'

    writes an image with this filename: 

      rose-70x46.png

    Finally to convert multiple JPEG images to individual PDF pages, use:

      convert *.jpg +adjoin page-%d.pdf

Two other options include -define jpeg:block-smoothing and -define jpeg:fancy-upsampling. Set the sampling factor with -define jpeg:sampling-factor. You can size the image with jpeg:size, for example -define jpeg:size=128x128. Finally, to restrict the maximum file size, use jpeg:extent, for example -define jpeg:extent=400kb.    		Note, JPEG is a lossy compression. In addition, you cannot create black and white images with JPEG nor can you save transparency.

To specify a single precision floating-point format, use -define quantum:format=floating-point. Set the depth to 32 for single precision floats, 64 for double precision, and 16 for half-precision. MPC RW Magick Persistent Cache image file format The native in-memory ImageMagick uncompressed file format. This file format is identical to that used by ImageMagick to represent images in memory and is read by mapping the file directly into memory. The MPC format is not portable and is not suitable as an archive format. It is suitable as an intermediate format for high-performance image processing. The MPC format requires two files to support one image. Image attributes are written to a file with the extension .mpc, whereas, image pixels are written to a file with the extension .cache.The most efficient data processing pattern is a write-once, read-many-times pattern. The image is generated or copied from source, then various analyses are performed on the image pixels over time. MPC supports this pattern.

    The identify program describes the format and characteristics of one or more image files. It also reports if an image is incomplete or corrupt. The information returned includes the image number, the file name, the width and height of the image, whether the image is colormapped or not, the number of colors in the image, the number of bytes in the image, the format of the image (JPEG, PNM, etc.), and finally the number of seconds it took to read and process the image. Many more attributes are available with the verbose option. See Command Line Processing for advice on how to structure your identify command or see below for example usages of the command.

The information returned includes the image number, the file name, the width and height of the image, whether the image is colormapped or not, the number of colors in the image, the number of bytes in the image, the format of the image (JPEG, PNM, etc.), and finally the number of seconds it took to read and process the image. Many more attributes are available with the verbose option. See Command Line Processing for advice on how to structure your identify command or see below for example usages of the command.

    [Install from Unix Source • Install from Windows Source]

    Chances are, ImageMagick is already installed on your computer if you are using some flavor of Unix, but that it is not installed if you are using some form of Windows. In either case, you can type the following to find out.

    $ identify -version

    -

    If the identify program executes and identifies itself as ImageMagick, you may not need to install ImageMagick from source unless you want to add support for additional image formats or upgrade to a newer version. You also have the option of installing a pre-compiled binary release. However, if you still want to install from source, choose a platform, Unix or Windows. Before installing from source, you may want to review recent changes to the ImageMagick distribution.

For example, what does one do if ImageMagick fails to configure or compile? Or what if you don't have administrator privileges and what if you don't want to install ImageMagick in the default /../usr/local folder?

    Install from Windows Source

    -

    Building ImageMagick source for Windows requires a modern version of Microsoft Visual Studio IDE. Users have reported success with the Borland C++ compiler as well. If you don't have a compiler you can still install a self-installing binary release.

    - -

    Download ImageMagick-windows.zip from www.imagemagick.org or a mirrors and verify its message digest.

    - -

    You can unpack the distribution with WinZip or type the following from any MS-DOS Command Prompt window:

    - -

    $ unzip ImageMagick-windows.zip

    -

    Next, launch your Visual Studio IDE and choose Open->Project. Select the configure workspace from the ImageMagick-6.7.5/VisualMagick/configure folder and press Open. Choose Build->Build Solution -to compile the program and on completion run the program.

    - -

    Press Next and click on the multi-threaded static build. If you are using the Visual Studio 6.0 IDE, make sure no check is next to the Generate Visual Studio 7 format option. Now press, on Next twice and finally Finish. The configuration utility just created a workspace required to build ImageMagick from source. Choose Open->Project and select the VisualStaticMT workspace from the ImageMagick-6.7.5/VisualMagick/ folder. Finally, choose Build->Build Solution to compile and build the ImageMagick distribution.

    [MIFF Header • MIFF Binary Data]

    The Magick Image File Format (MIFF) is ImageMagick's own platform-independent format for storing bitmap images. It has an advantage over other image formats in that it stores all metadata known to ImageMagick (e.g. image color profiles, comments, author, copyright, etc.), whereas, other formats may only support a small portion of available metadata or none at all. A MIFF image file consist of two sections. The first section is a header composed of keys describing the image in text form. The next section is the binary image data. We discuss these sections in detail below.

This makes it very suitable for Web CGI scripts. You must have ImageMagick 6.5.5 or above and Perl version 5.005_02 or greater installed on your system for PerlMagick to build properly.

    There are a number of useful scripts available to show you the value of PerlMagick. You can do Web based image manipulation and conversion with MagickStudio, or use L-systems to create images of plants using mathematical constructs, and finally navigate through collections of thumbnail images and select the image to view with the WebMagick Image Navigator.

    To support variable pixel channels in the MagickCore API, pixel handling has changed when getting or setting the pixel channels. You can access channels as an array, pixel[i], or use an accessor such as GetPixelRed() or SetPixelRed(). There are some modest changes to the MagickWand API. Magick++ and PerlMagick should behave exactly as it does for ImageMagick version 6.

    +

    The shell API (command line) of ImageMagick version 7 is also undergoing +a major overhaul, with specific emphasis on the ability to read 'options' not +only from the command line, but also from scripts, and file streams. This +allows for the use of 'co-processing' programming techniques or performing +image handling using 'deamon/server backends', and even multi-machine +distributed processing.

    + +

    With shell API overhaul other improvements are being made, including: +better reporting of which option failed, the consolidation and depreciation of +options, and more global use of 'image properities' (more commonly known as +'percent escapes' in option arguments.

    +

    We intend to make ImageMagick version 7 available as an Alpha release by the mid-year 2012. Look for a Beta release sometime in late 2012. An official ImageMagick version 7 release depends on how smoothly the Beta cycle progresses. During the Beta cycle, version 6 developers can attempt to port their software to version 7.

    During the ImageMagick version 7 development cycle and release, we will continue to support and enhance version 6 for a minimum of 10 years.

    Previously, grayscale images consumed 4 channels: red, green, blue, and alpha. With version 7, grayscale consumes only 1 channel consuming far less resources as a result. However, there may be unintended consequences. With 1 channel, all image processing algorithms write to this one channel. Drawing yellow text on a grayscale image will produce gray lettering. To get the expected results, simply modify the colorspace to RGB (e.g. -colorspace rgb).

    In addition, all deprecated MagickCore and MagickWand methods are no longer available in version 7.

    Command-line Interface

    + + +

    Shell API or Command-line Interface

    -

    By default, most algorithms update the red, green, blue, black (for CMYK), and alpha channels. If appropriate, alpha is blended with red, green, blue, and black. For some algorithms, it only makes sense to copy alpha. For these cases, use the -channel option (e.g. convert castle.gif -channel RGB -negate castle.png).

    -

    The -convolve option no longer normalizes the kernel argument and accepts non-square user defined kernels.

    + +

    As mentioned the primary focus of the changes to the Shell API or Command +Line Interface is the the abstration so that not only can 'options' be read +from command line arguments, but also from a file (script) or from a file +stream (interactive commands, or co-processing).

    + +

    To do this the CLI parser needed to be re-written, so as to always perform +all options, in a strict, do-it-as-you-see it order. Previously in IMv6 +options were performed in groups (known as 'FireOptions), this awkwardness is +now gone. However the strict order means that you can no long give operations +before providing an image for the operations to work on. To do so will now +produce an error.

    + +

    Error reporting is now reporting exactly which option (by argument count on +command line, or line,column in scripts) caused the 'exception'. This is not +complete as yet but getting better. Also not complete is 'regard-warnings' +handling or its replacement, which will allow you to ignore reported errors +and continue processing (as appropriate due to error) in co-processes or +interactive usage.

    + +

    The parenthesis options used to 'push' the current image list, and image +settings (EG: '(' and ')' ) on to a stack now has +a completely seperate image settings stack. That is parenthesis 'push/pull' +image lists, and curly braces (EG: '{' and '}' ) will +'push/pull' image settings.

    + +

    Of course due to the previously reported changes to the underlying channel +handling will result be many side effects to almost all options. Here are some +specific

    + +

    Most algorithms update the red, green, blue, black (for CMYK), and alpha +channels. Most operators will blend alpha the other color channels, but other +operators (and situations) may require this blending to be disabled, and is +currently done by removing alpha from teh active channels via +-channel option. (e.g. convert castle.gif -channel RGB +-negate castle.png).

    + +

    Reading gray-scale images will generate a image with only one channel. If +that image is to then accept color the -colorspace setting needs to +be applied to expand the one channel into separate RGB (or other) channels. +

    + +

    Command Changes

    +
    +
    magick
    +
    The "magick" command is the new primary command of the Shell + API, replacing the old "convert" command. This allows you to + create a 'magick script' of the form "#!/path/to/command/magick + -script", or pipe options into a command "magick -script + -, as abackground process.
    + +
    magick-script
    +
    This the same as "magick", (only command name is different) + but which has an implict "-script" option. This allows you to + use it in an "env" style script form. That is a magick script + starts with the 'she-bang' line of "#!/usr/bin/env + magick-script" allowing the script interpreter to be found anywhere + on the users command "PATH". This is required to get around + a "one argument she-bang bug" that is common on most UNIX systems + (including Linux, but not MacOSX).
    + +
    + +

    New Options

    +

    ImageMagick version 7 supports these new options, though most are limited +to the "magick" command, or to use in "magick" +scripts.

    + +
    +
    { ... }
    +
    Save (and restore) the current image settings (internally known as the + "image_info" structure). This is automatically done with parenthesis (EG: + '(' and ')') is "-regard-parenthesis" has + been set, just as in IMv6. Caution is advised to prevent un-balanced + braces errors.
    + +
    --
    +
    End of options, to be used in IMv7 "mogrify" command to + explictally separate the operations to be applied and the images that + are to be processed 'in-place'. (not yet implemented). However if + not provided, "-read" can still be used to differentiate + secondary image reads (for use in things like alpha composition) from + the 'in-place' image being processed.
    + +
    In other commands (such as "magick") it is equivelent to a explict + "-read" (see below) of the next option as a image (as it was in + IMv6).
    + +
    -channel-fx expression
    +
    +

    exchange, extract, or copy one or more image channels.

    + +

    The expression consists of one or more channels, either mnemonic or numeric (e.g. red, 1), separated by certain operation symbols as follows:

    + +
    +  <=>     exchange two channels (e.g. red<=>blue)
+  =>      copy one channel to another channel (e.g. red=>green)
+  =       assign a constant value to a channel (e.g. red=50%)
+  ,       write new image with channels in the specified order (e.g. red, green)
+  ;       add a new output image for the next set of channel operations
+  |       move to the next input image for the source of channel data
+
    + +

    For example, to create 3 grayscale images from the red, green, and blue channels of an image, use:

    + +
    +  -channel-fx "red; green; blue"
+
    + +

    A channel without an operation symbol implies separate (i.e, semicolon).

    + +
    + +
    -exit
    +
    Stop processing at this point. No further options will be processed after + this option. Can be used in a script to force the "magick" + command to exit, without actually closing the pipeline that it is + processing options from.
    + +
    May also be used as a 'final' option on the "magick" command + line, instead of a implicit output image, to completely prevent any image + write. ASIDE: even the "NULL:" coder requires at least one + image, for it to 'not write'! This option does not require any images at + all.
    + +
    -read {image}
    +
    Explicit read of an image, rather than an implicit read. This allows you + to read from filenames that start with an 'option' character, and which + otherwise could be mistaken as an option (unknown or otherwise).

    Classification

    Classification builds a color description tree for the image. Reduction collapses the tree until the number it represents, at most, is the number of colors desired in the output image. Assignment defines the output image's color map and sets each pixel's color by reclassification in the reduced tree. Our goal is to minimize the numerical discrepancies between the original colors and quantized colors. To learn more about quantization error, see Measuring Color Reduction Error.

    Classification begins by initializing a color description tree of sufficient depth to represent each possible input color in a leaf. However, it is impractical to generate a fully-formed color description tree in the classification phase for realistic values of Cmax. If color components in the input image are quantized to k-bit precision, so that Cmax = 2^k-1, the tree would need k levels below the root node to allow representing each possible input color in a leaf. This becomes prohibitive because the tree's total number of nodes:

    The normalized error measurement can be used to compare images. In general, the closer the mean error is to zero the more the quantized image resembles the source image. Ideally, the error should be perceptually-based, since the human eye is the final judge of quantization quality.

    [Example Usage • Option Summary]

    Stream is a lightweight tool to stream one or more pixel components of the image or portion of the image to your choice of storage formats. It writes the pixel components as they are read from the input image a row at a time making stream desirable when working with large images or when you require raw pixel components.
